Manufacturers : Cameras and optics : Binoculars and telescopes

Binoculars are used to magnify the user's vision, to permit an apparently closer view of the object or scene of interest. Typically, binoculars have comprised two barrels, each containing glass object and eyepiece lenses, glass prisms, and focusing mechanisms. Binoculars have a pair of right and left telescopic optical systems, optical axes of which are arranged in parallel. They're are provided with various adjusting mechanisms such as a focusing mechanism, a diopter difference adjusting mechanism, and a magnifying power changing mechanism. Electronic binoculars are capable of recording image data in a storage medium. The electronic binoculars are generally provided with an imaging unit, ocular units, and an image-signal processing unit. Electronic binoculars have the advantage of night vision and are widely used in the military to provide soldiers, aviators and sailors with the ability to view objects at night or during other low light conditions. Night vision binoculars typically include an image intensifier tube that converts infrared energy into visible light.

A telescope is an instrument for collecting and examining electromagnetic radiation, especially an arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant object. Telescopes range in size from small, readily portable ones to large fixed ones which are permanently located in observatories. The smaller telescopes are commonly used by students, hobbyists and amateur astronomers. The larger telescopes are generally only used by researchers and professional astronomers. Common types of telescopes include refractor telescopes, reflector telescopes, Schmidt-Cassegrain telescopes and Maksutov-Cassegrain telescopes. Reflector telescopes generally employ a concave primary reflector which collects and focuses light incident upon the reflector surface through the telescope's aperture and a smaller secondary reflector to direct the reflected light to the telescope's eyepiece. Refractor telescopes have a light collecting objective lens which focuses the collected light upon an eyepiece. The eyepiece, in cooperation with the objective lens, provides the desired magnification. Schmidt-Cassegrain telescopes are similar to reflector telescopes, except that the secondary mirror of a Schmidt-Cassegrain telescope reflects the collected light through an opening in the primary mirror instead of through an opening in the tube. The Cassegrain telescope consists principally of a paraboloidal primary mirror and a hyperboloidal secondary mirror positioned between the primary mirror and the primary mirror's focal point. A Gregorian telescope has a primary mirror and a secondary mirror, with the distance between the primary and secondary mirrors being greater than the focal length of the primary mirror. Medical endoscopes are a form of telescope which is widely utilized to view internal regions of the human body during diagnostic, surgical, and other medical procedures. Endoscopes typically include a long, thin, rigid or semi-rigid optical cylinder affixed to a viewing mechanism.
